水性光引发剂(4-苯酰基)苯甲基铵-N-十二烷基-N,N-二甲基溴化物的合成

Synthesis of Novel 4-Benzoyl-N-dodecyl-N,N-dimethyl Benzenemethanammonium Bromide

以4-甲基二苯甲酮为原料,经溴化合成4-溴甲基二苯甲酮,再与二甲基十二胺反应合成新型的光引发剂(4-苯酰基)苯甲基铵-N-十二烷基-N,N-二甲基溴化物,对新化合物结构进行了IR,MS,1HNMR表征。产品纯度大于98%,收率大于81%(以4-溴甲基二苯甲酮计)。对产品的光引发性能进行了初步研究。

4-Benzoyl-N-dodecyl-N,N-dimethyl benzenemethanammonium bromide was synthesized through the reaction of 4-bromomethyl benzophenone with dodecyl dimethyl amine. Its structure was characterized by MS, IR and 1H NMR. The purity of the product was 98%, and the yield was 81% （based on 4-Bromomethyl benzophenone）.
